Don't forget Gov Mickelson died in plane crash.
Also, don't forget those two Plastic Surgeons that died in two different plane crashes. One into Sioux Falls residential area, and one out in the wilds outside Aberdeen that took days for a hunter to finally find the wreckage.
Then, the Oil people that for some stupid reason tried to fly out of Pierre to go back home during a freaking BLIZZARD! That one didn't make ANY sense!
